I have just been out testing these tires on my tamiya cr-01 and my 2,2 tuberframe crawler/trail car.I ride in a forest with moss branches roots and sand also,no rocks but only big stones.In these types off surface these tires rocks,they beat proline moab m2 and flat iron both in 2,2.And also the stock tamiya crawlertires by a mile.These tires are fantastic and they come in different coloured alu rock rings to suit youre car,and the tire thread lookes like it could drive right through the amazones or somewhere like it.The rim material also feels as nice as proline eightshooter beadlock wheels.When we can buy so great quality products at these prices why looke else where for some for more expensive but not better products ?So i can only say all thumbsup from me on buying this rim tire set,now i want to go try a set off the alu ones from 3racing to see if they are as good as these ones
